Embodiment 1

[0037] According to an embodiment of the present invention, a three-dimensional imaging technology for the exploration of abandoned mine pits is provided, which is specifically used to measure an underground coal mining pit in Yulin, Shaanxi. Specifically include the following steps:

[0038] Step 1: The measurement drone enters the abandoned mine pit and moves forward along the tunnel. During this process, the drone needs to be manually transported to the abandoned mine pit, and after setting relevant parameters, the drone flies according to the predetermined procedure .

[0039] Step 2: Measure the left and right sides of the UAV and equip the first laser ranging device symmetrically. The measured distance from the UAV to the left side of the mine pit is A1, and the measured distance from the UAV to the right side of the mine pit is A2; measure the UAV up and down Both ends are symmetrically equipped with a second laser ranging device, the measured distance between the UAV ...

Abstract

The embodiment of the invention discloses a three-dimensional imaging technology for waste pit exploration, which comprises steps: a measuring drone enters a waste pit and moves forward along the tunnel; the left and right sides of the measuring drone are symmetrically equipped with first laser distance measuring devices, the upper and lower ends of the measuring drone are symmetrically equipped with second laser distance measuring devices, a drone control system receives values of distances A1 and A2, and the drone control system adjusts the flight attitude of the drone according to comparison between the A1 and A2 values; the drone control system receives values of distances B1 and B2, and drone control system adjusts the flight attitude of the drone according to comparison between the B1 and B2 values; and a three-dimensional scanner arranged at the tail part of the drone performs rotary scanning with the advancing direction of the drone as an axis, a scanned image is transmitted toa modeling device, and the modeling device builds a three-dimensional image of the pit. Through the method of the invention, the three-dimensional image of the pit can be accurately built, and the amount of the backfill filler can be determined through the three-dimensional image of the pit, thereby improving the budget accuracy of the pit backfilling project.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of pit restoration, and in particular relates to a three-dimensional imaging technology for exploration of abandoned mine pits. Background technique [0002] In the mining process of coal and various mineral resources, large and small mine pits will be produced, and if these mine pits cannot be backfilled in time, water storage will occur after rainfall, which may cause landslides, water seepage, etc. Natural disasters not only destroy the original geological features, but also may endanger personal and property safety. [0003] In order to solve the problems caused by the above-mentioned mine pits, people began to study backfilling the mine pits, especially underground mine pits. However, due to the large size of the pit, it is difficult to accurately measure the size of the pit using traditional measurement methods, so that the amount of backfill filler to be applied cannot be ac...
